4YR OLD TV NEVER BEEN TOUCHED UPPER CORNERS OF THE TV LOOKS LIKE 2 CLOUDS BLOCKING THE LIGHT AND FADES TOWARD THE CENTER DOWNWARD ONLY REALLY SHOWS UP UNDER BRIGHTER CONDITIONS OF THE SCREEN PICTURE QUALITY IS WHAT IT USED TO BE DOES THIS THING NEED CLEANED INTERNALLY? COLOR WHEEL?????? I HAVE HAD THIS MODEL FOR TWO YEARS AND THERE ARE SHADOWS ON BOTH THE BOTTOM CORNERS.SOMETIMES THEY FADE AWAY BUT ALWAYS COME BACK, WHAT IS THE PROBLEM.
I would check for dust particles before I attempted any type of repair on the unit.
Dust particles will appear as dark spots that are larger than the size of an individual pixel. It must first be determined if the particle(s) are on the LCD panels or the screen.
